I recently purchased a used PC 7529 router off feebay for more than I shoiuld have paid. The router looked close to new and I gave the jackass $165 for it. I tested it at first and it ran so I assumed all was well.

After the return period was over I finally needed to use the thing and it is so weak it barely routes a dado in soft maple. My 690 routers route rings around this beast. I have another identical router mounted for RP door styles and it has plenty of power. I checked the brushes and they look fine.

So what would be the cause this 2.25hp router being so weak? What can I do to get it up to snuff without paying for a new one? Do you think it could be the field and/or the armature?

open it up. blow out the dust pay particular attention to the switch enclosures. check the brushes. replace if needed. try to seal it so that the dust cant get back into the switch areas, use a little SEEP (Super Elasic Sealastic Plastic). You can clean the armature with a pencil eraser
